Measurements have been made using a two component LDV system for turbulent flows between two concentric cylinders with the inner cylinder rotating and the outer cylinder stationary at the radius ratios of 2.88 and 7.1, and at large Taylor numbers. The results are compared with those measured in similar flow geometries at smaller radius ratio using hot wires. The mean velocity profiles have been presented using various scalings, and it is found that under the scaling of wall shear velocity and local distance from the cylinder surface (inner scaling), the data collapse better. A power law is found to fit the data well in the entire interior region apart from the two viscous zones near the cylinder surfaces. The data can also be fitted using a logarithmic law similar to that used in unidirectional wall shear flows, but with different constants and within smaller regions.
